' Patented Feb. 4, 1919 Application filed December 18, 1917. Serial No. 207,708.

To all. whom it may concern:

Be it known that I, JAMES Cnnnonouz, citizen of the United States, residing at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Photographic-Film Cameras; and. I do herebyldeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

This invention relates to improvements in photographic cameras, and more partlcularly in so-called folding ocket cameras :adapted to employ flexible lm' mounted on -spools.

The articular object of the invention is to provide means in a camera of the character defined for simultaneously releasing both ends of the feed spool for the purpose of removing the same and maintaining the ivots therefor separated until a new spool has been inserted, and to similarly provide means for readily and quickly releasing or engaging' one end of the take-up spool opposits that engaged by the winding key for taking up film at intervals from the feed spool.

The invention has for its further object to to provide means of the character set forth which are contained entirely within the camera housing so as to be inaccessible from the exterior thereof, thus preventing accidental operation of thesame and a conse- 85 quentrelease of a contained spool or spools.

The invention may be variously embodied and in the accompanying drawings I have illustrated only "the preferred embodiment thereof.

In said drawings: Figure -1 is a view in elevation of the rear of afolding pocket camera having its rear Wall partially broken away to expose to view the film spool-engaging and releas ing means constructed in accordance with the invention.

. Fig. -2 is a sectional view on the line 2-2 of Fig. -1---.

Fi 3- is a. detail perspective view showing one of the operating parts of the film spool engaging and releasing means.

Fig. -4- is a spction similar to Fig. -2- on the line 4-4 of Fig. --1 showing the mechanism for engaging and releasing the feed spool.

.;Fig. -5-- is a detail transverse section on the line .5- of Fig. -4-

Figs. --t--- and --7 are respectively detail perspective views of pivot-carrying. springs employed.

In said drawings A. and B indicate the side walls of a camera housing which has rounded end portions. The said walls A and B are relatively thick and through one end of one thereof a winding key C projects, the same being equipped with a crosshead B adapted to engage in the transverse slot in one end of the hub E of a film spool of the standard kind employed in kodaks or cameras of this character. The said winding key C is normally held at the inner limit of its movement in engaging relation to a. film spool by means of a spring, the latter being omitted from illustration and constituting no part of the present invention. Said key is released from engagement with the film spool. by manually forcing said key outwardly against the action of its engaging spring, and is so held during the operation of removing and replacing spools.

in the wall A opposite the point in the wall B wherein the winding key G is mounted there is a recess F which is covered by a metal plate G having a central opening therein. Said plate and a similar plate H mounted upon the inner face of the wall B and having a central opening through which the Winding lrcy C projects are providcdwith projections l to engage the peripheraledgcs of the flanges J of the film spool for readily positioning the same so that the openings in the ends of said spool will become disposed respectively opposite the winding key C and the pivot member K normally projcctin through its central opening in the plate The said pivot. member K is mounted upon the free end of an arm L of a flat s ring M which lies normally in contact with t is front wall N of the housing, and is provided at its other end with a short flange or projection 1 0 O. The said spring is contained in a recess P in the front wall N and said recess is spanned contiguous to its ends by rods Q underneath which the said spring M projects. The rod Q contiguous to the recess F constitutes a fulcrum on which the arm L carryin the pivot member K turns as a fulcrum when said spring is bowed, as shown in dotted lines in Fig. 2. Disposed parallcl with the recess P is another recess R inn" adapted to cont:

in which the inner end of a lever S is contained. The latter rigid with a shaft '1" lies underneath and partially bows the fist spring M between its ends as shown in F ---52. The said. flat portion normally-lies mreliel with "elm front Willi of the housing, and when turned through an arc of nineiay degrees. indi ted in Fig. --2-, serves to bow the spring in to an extent soflioient to cause the arm L thereof to turn through sufficient arcs to entirely Withdraw the pivot n'leinbei li from e 'ogeineni in the end of the spool l), thus B sing said and of said spool.

The spring Z ii new end. oi? the lions-- die feed spool is pro Vided with two said ar s L at opposite ends, each of which. a a pivoc member K and which is boi mechanism identicel with that horeinl; e described; both said {LI'I'HS being thus so o2 Lineously turned as shown in deified lines 1 Fig. :l to release both ends of the oone cl spool, as will be obvious.

It Will be understood, oil: worse, that the aforesaid mechanism is capable of some modifications and variations without dogmrt ing from the invention as defined in the oppended claims.

I claim in y invention:

1. In a film spool comers. including a housing; having a posterior opening and e. EGlnOVablQ cover for some, 9. pair of opposed pivot members disposed Within the casing and adapted to engage opposite ends of e film-semi, and a manually member disposed within the owners housing and operable only upon opening the C(Wfil for the said posterior opening operatively associated with said PlVQikIHGIUbBXS for siin iteneously moving the same in opposite diroolrions.

"in film-spool camera, a of opweapon In a film-spool camera, impair of opg posed pivot carrying members disposed wlthw in the casing, a flGKI DlB element. Integral:

therewith for noi'inzilly 'l olding the some in engaging relation to opposite ends of a film spool. fulcrum elements on which said members are adapted to turn, and amanually operable member operatively associated with said flexible element and said fulcrum elements for flexing the former for simultaneously throwing the pivot-carrying members out of engaging it'elation 'Cosaid filmspool.

4:. In a. film spool comers, a film spool pocket, e flexible element mounted in the bot tom thereof and provided wiil] end flanges, a. pair of fulci'uin members monnfedto engage said flanges adjacent to their junction wvitli the middle poi-tum of said flexible member, at least, one of said flanges carrying a, pivot pin. normally positioned to engage in one end of film spool disposed in said pocket. and a manually operable element for flexing said flexible member and 00- operating with said fulcrum elements for effeciing movement of said pivot pin carrying flange so throw the ivot pin out of eneging relation to the film spool.

5. in a film-spool camera, spool chamber-s, & substantially Li-shaped spring disposed in each thereof, retaining means engaging the some at its elbows. a. pivoted lever actuated member disposed in engagement with the middle portion of each spring and adapted when turned through a predetermined arc to bow said middle portion and efiect simultaneous opposite movement of the arms. thereof, recesses in the side Walls of the housing containing said arms, and spool-enga ing pivot members mounted at the free on s of said arms.
